Minimize What is Sentinel-2?
Web Content Image

The Sentinel-2 mission is a land monitoring constellation of two satellites that will provide high resolution optical imagery and provide continuity for the current SPOT and Landsat missions.

The mission will provide a global coverage of the Earth's land surface every 10 days with one satellite and 5 days with 2 satellites, making the data of great use in on-going studies.

The satellites will be equipped with the state-of-the-art MSI (Multispectral Imager) instrument, that offers high-resolution optical imagery.

Help wanted on tracking biodiversity from space

12 August 2015

Conservation organisations and space agencies are being called on to join forces to decide how changes in biodiversity can be monitored globally. What, exactly, should be measured by satellites?
